Machine concept

For the development of this machine series, the characteristics of the very successful new machine generation from Liebherr was systematically transferred to the application of the universal machines LC 600 LC 2000.

The necessary flexibility for different applications is achieved with a two-piece machine bed. With this concept, the machines can be optimally configured to customer-specific requirements. The self-supporting, very rigid design allows a machine installation directly on the floor, without a special foundation.

Chip removal is accomplished through the machine bed with the chip conveyor arranged lengthwise. The machine bed and the laterally arranged coolant lubricant tanks hold approx. 800l of coolant.

Highlights of the Liebherr LC 600 - 2000 gear hobbing machine

The LC 600 - 2000 is specifically designed for the machining of large-modulus gears and shafts as well as internal gears. All models in this series are based on modular components with different tables, heads and counter column assemblies.

Swivelable tailstock arm

NC-controlled tailstock arm with programmable travel range and adjustable clamping force

Hydraulic steady rest with self centering function
Diameter: 100 - 520 mm
With hydraulic swivel device on the counter column for ergonomic loading of long shafts.
